ActiveBuilding components and building elements—Thermal resistance and thermal transmittance—Calculation methods
建筑构件和建筑单元 热阻和传热系数 计算方法
Application Summary AI generated
This standard specifies calculation methods for determining the thermal resistance and thermal transmittance of building components and elements, such as walls, roofs, floors, and windows. It is applied in the construction industry for building energy efficiency design, thermal performance evaluation, and compliance verification with Chinese energy codes. Engineers and architects use it to calculate heat transfer through multi-layer constructions under steady-state conditions.
